Proximity-induced superconductivity and Josephson critical current in quantum spin Hall systems
Hoi-Yin Hui, Alejandro M. Lobos, Jay D. Sau +1
We consider recent experiments on wide superconductor-quantum spin Hall insulator (QSHI)-superconductor Josephson junctions, which have shown preliminary evidence of proximity-indu…
Majorana Fermions in Chiral Topological Ferromagnetic Nanowires
Eugene Dumitrescu, Brenden Roberts, Sumanta Tewari +2
Motivated by a recent experiment in which zero-bias peaks have been observed in scanning tunneling microscopy (STM) experiments performed on chains of magnetic atoms on a supercond…
Excitonic and Nematic Instabilities on the Surface of Topological Kondo Insulators
Bitan Roy, Johannes Hofmann, Valentin Stanev +2
We study the effects of strong electron-electron interactions on the surface of cubic topological Kondo insulators (such as samarium hexaboride, SmB). Cubic topological Kondo i…
Majorana fermions in ferromagnetic chains on the surface of bulk spin-orbit coupled -wave superconductors
Hoi-Yin Hui, P. M. R. Brydon, Jay D. Sau +2
Majorana fermion (MF) excitations in solid state system have non-Abelian statistics which is essential for topological quantum computation. Previous proposals to realize MF, howeve…
Generalized Eilenberger theory for Majorana zero-mode-carrying disordered -wave superconductors
Hoi-Yin Hui, Jay D. Sau, S. Das Sarma
Disorder is known to suppress the gap of a topological superconducting state that would support non-Abelian Majorana zero modes. In this paper, we study using the self-consistent B…
Magnetic catalysis and axionic charge-density-wave in Weyl semimetals
Bitan Roy, Jay D. Sau
Three-dimensional Weyl and Dirac semimetals can support a chiral-symmetry-breaking, fully gapped, charge-density-wave order even for sufficiently weak repulsive electron-electron i…
